100%成功整合 Spring Boot +Zookeeper + Dubbo

> 序言

Dubbo是Alibaba开源的分布式服务框架，它最大的特点是按照分层的方式来架构，使用这种方式可以使各个层之间解耦合（或者最大限度地松耦合）。从服务模型的角度来看，Dubbo采用的是一种非常简单的模型，要么是提供方提供服务，要么是消费方消费服务，所以基于这一点可以抽象出服务提供方（Provider）和服务消费方（Consumer）两个角色。

> 下载

由于Dubbo要使用Zookeeper作为服务注册中心

Zookeeper下载地址:[点我进入下载目录][Link 1]

> 安装 Zookeeper

其实解压是不需要任何操作的

**唯一需要注意的一步：**

在Zookeeper目录下的conf 有一个**zoo\_simple.cfg** 需要将它改名为**zoo.cfg**，不然zookeeper在读取配置文件时会报错找不到

> 运行Zookeeper

使用管理员运行CMD,进入Zookeeper的bin目录下

运行 **zkServer.cmd(仅限windows)**

> 编写Dubbo的各方面代码(生产者 && 消费者)

首先 需要创建两个 Spring Boot 项目 （provider / consumer）

先对 provider 进行操作

**修改 provider -》 pom.xml**

** 创建Provider 服务接口与实现类**

// 接口
    package cm.marding.provider.service;
    
    public interface UserService {
        public void test();
    }

// 实现类
    package cm.marding.provider.service.impl;
    
    import cm.marding.provider.service.UserService;
    import org.springframework.stereotype.Service;
    
    @Service("dubboService")
    public class UserServiceImpl implements UserService
    {
        @Override
        public void test() {
            System.out.println("this is a test message");
        }
    }

**创建 provider.xml **

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
           xsi:schemaLocation="http://www.springframework.org/schema/beans
    	http://www.springframework.org/schema/beans/spring-beans.xsd
    	http://code.alibabatech.com/schema/dubbo
    	http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
    
        
        <dubbo:application name="provider"/>
        
        <dubbo:registry  protocol="zookeeper" address="zookeeper://127.0.0.1:2181"/>
        
        <dubbo:service interface="cm.marding.provider.service.UserService" ref="dubboService"></dubbo:service>
    </beans>

**最后,启动类需要添加@ImportResource 引用 provider.xml**

package cm.marding.provider;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.context.annotation.ImportResource;
    
    @SpringBootApplication
    @ImportResource("classpath:provider.xml")
    public class ProviderApplication {
    
        public static void main(String[] args) {
            SpringApplication.run(ProviderApplication.class, args);
        }
    }

到此为止 Provider生产者 编写完成

> 将编写好的 项目 使用 mvn install 去进行生成 Jar 的操作 （为了让消费者 引用）

**紧接着 编写消费者** 的 **pom.xml**

**创建 consumer.xml**

<?xml version="1.0" encoding="UTF-8"?>
        <beans xmlns="http://www.springframework.org/schema/beans"
               xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
               xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://code.alibabatech.com/schema/dubbo
        http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
            
            <dubbo:application name="consumer" />
            
            <dubbo:registry  protocol="zookeeper" address="zookeeper://127.0.0.1:2181" />
            
            <dubbo:reference interface="cm.marding.provider.service.UserService" id="dubboService"></dubbo:reference>
    </beans>

编写消费者 Controller

package cm.marding.consumer.controller;
    
    import cm.marding.provider.service.UserService;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    @RestController
    public class PageController {
        @Autowired
        private UserService userService;
        @RequestMapping("/")
        public  String  index(){
            userService.test();
            return "success";
        }
    }

**注意 启动顺序 一定是 Zookeeper -> 生产者 -> 消费者 不然 会报错**

**以下为 成功的日志提示**
